At the surface of the moon, a gravitational force of 120 N acts on the cosmanaut, which force of gravity acts

At the surface of the moon, a gravitational force of 120 N acts on the cosmanaut, which force of gravity acts from the moon on the same cosmanaut in a spacecraft moving in a circular orbit around the moon at a distance of three lunar radii from its center.

These tasks: Fт1 (gravity at the surface) = 120 N; R (distance from the center of the Moon) = 3Rl.

To determine the gravitational force acting on the considered cosmonaut in the spacecraft, we use the formula: Ft2 = m * G * ml / R ^ 2 = m * G * ml / (3Rl) ^ 2 = (Ft1 / gl) * G * ml / ( 3Rl) ^ 2 = (Ft1 / (G * ml / (Rl) ^ 2) * G * ml / (3Rl) ^ 2 = Ft1 / 32 = 120/9 = 13.33 N.

Answer: The cosmonaut under consideration is affected by a gravitational force of 13.33 N.
